Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
When you have the prism's base area (
) you just have to multiply:

(V = volume)

Answer:
Simply search for surface area formula for pyramid on goole and plug the numbers into the formula!! Thank you so much!!
Step-by-step explanation:
So, you already know that you have to multiply the value of 7 by the variable and the number inside of the parentheses. So, 7 x A = 7A, and 7 times -6 equals -42. So, your answer would most likely be 7a - 42.
